Cisco uBR10012 routers are divided into subsystems for more efficient problem solving.
Before You Call for Technical Assistance
If you are unable to easily solve the problem, contact a customer service representative for assistance and further instructions. Provide the representative with the following information:
•Date you received the router
•Chassis serial number
•Type of software and release number
•Brief description of the problem you are having
•Brief explanation of the steps you have taken to isolate and resolve the problem
•Maintenance agreement or warranty information
Problem Solving Using a Subsystems Approach
The key to solving problems with the system is isolating the problem to a specific subsystem. Because a startup problem is usually caused by a single component, it is more efficient to first isolate the problem to a subsystem rather than troubleshoot each component in the system. For these troubleshooting procedures, consider the following subsystems:
•Power
•Processor
•Cooling
The following sections help you isolate a problem to one of these subsystems and direct you to the appropriate troubleshooting section.
